To att wiz/ont it may concern.'

Be it known that I, ANDREW RAwsoN J EN- NiNGs, a subject of theKingof-Great Britain, residing at 1#1181 Audrey House, Ely

Place, in the city of London, England, have invented certain new anduseful Improvements in and Relating to Adding-Machines, and do herebydeclare the nature of this invention and in what manner -the same is tobe performed to be'particularly described and ascertained in and by thefollowing statement.

This invention relates to adding machines for use in recording sums ofmoney or the like in columns and for listing the amount of checks,drafts, notes, and the. like, adding the sum totals, printing the setsof figures in columnar order, and the totals at the foot ,of thecolumns.i

The invention aims to provide an' adding machine for the purpose setforth which shall be simple in its construction, so set up as to avoidthe employment of gearing asmuch as possible, eflicient in -its use,strong, durable, accurate in its operation, conveniently operated,readily set up, and comparatively inexpensive to manufacture.'

With the foregoingand other objects in view, the invention consists inthe novel conofthey machine with the case removed.

struction, combination and arrangement of parts hereinafter morespecifically described and illustrated in the accompanying vdrawings,wherein is shown the preferred embodiment of the invention, but it is tobe understood that changes, variations, and modifications can beresorted to, which come within the scope of the claims hereuntoappended.

. In describing the invention in detail, reference characters denotecorres onding parts through the several views, an( in which--V Figure 1is a'sideview of the left-hand half of a machine in'accordancewith thisiii-vention partly insection and with the side plate rer'noved `so aslto enable parts of the machine "to bec'learlyA shown'iYV Fig. A1a is aview similar to'Figdl" but showing the right-handhalf vof the machineFig. 2 is a plan view illustratingy the'cipher 'moving levers .and aportion ofthe-type quadrants.

die and total key connections. Fig. 10 is a Vside elevation showing theactual adding and carrying principle, and, Fig. '11 is a perspectiveview showing two of the carrying levers with their connections'.

Referring to the drawings byV reference characters the niachiuecomprises a horizontally-extending shaft 35 journaled in the sides ofthe frame 35a, and upon the shaft 35 are loosely mounted collars 35h, towhich are fixed the toothed wheels c. Preferably the number of teeth oneach of said wheels is 40,

REISSUED l exceptfor pence columns in sterling niachiues, when thenumber of teeth would be 48.

In the case of decimal adding machines, it will be found convenient toemploy wheels c, each having forty teeth. The collars 35 space thewheels c suitable distances apart.

' The machine casing is formed in the front thereof with a lurality ofslots a', through which project t -e keys a, so as to enable thesaidkeys to be conveniently reached by the operator. `Ait .the side ofeach series of' keys and on the front of the machine casing the digitsa2 are provided, these digits beingr from 1 to 9. Each set of keys a iscarried by a quadrant o, which terminates at its lower end in aconnecting bar ixed upon one of the collars 35", and the said connectingbar has its lower portion extending rearwardly and upward edge of saidportion of the connecting bar is in alinement witha vertical linethrough the center of the shaft 35 so that the first one of the'type dwill bev rearwardly of the hammer to be hereinafterA referred to.Pivoted to the off-set a5, as at d?, is a vertically-extending ty ecarrying arm d, provided at its top'witlh a cipher type p, and the saidarm d3 in that side which op oses the front of the portion a.4 is formedwitli a notch d to permit of the entrance of a shifting lever in themarmer as hereinafter set forth, so as which is-below t Ul x adaptedy toshiftably rsupport `its respective vquadrant o and sector armee upon theshaft 35, and the 'said' connecting bars constitute means for connectingthe type-carrying sector arm with the keycarrying quadrant, so lthatwhen the keycarrying quadrant is I shifted downwardly, the type-carryingsector arm will move forwardly, andthe arm (Z3 will I also have acorresponding movement to the the cpiadrants are moved downwardly, the4whee s c being held"stationary owing toa locking device engagingbejfweer'i the teeth thereof.y The lockingdevice `consists of ahorizontally-extending bar carried at the upper end of a pair of arms 1,which are pivoted at their lower endto theshaft 2. Z'lhe bar f isretained in normal engagement between the teeth of the wheels c by meansof'a' spring 3,' connected at Aone end to one of the arms 1, 'and at'the other end to thesupportSa.

The manner in which the barf is movedv from engagement between the teethofthe Wheels' c will presently be referred to. l

v The top 3b of the` machine r'zasiiig, forwardly thereof, is formedwith an opening 3c to permit of the operation of'ahammer .e to ma e arecord upon a recording strip of lpaper 14, the said strip unwinding'off the ro 14",

passing underand over the guides-14,l 149,

and between the 4friction rollers 41, the strip roller 42.

of papery 14 being Vpositioned by the guides 14c within the opening 3below the hammer e. Arranged below the strip of paper I14 and retainedin the Aopening `3c through the medium of the guides 19a is an inkribbon, which travels between the guides 191" and off of lthe The ribbon19 also travels under the guides 1'9" and upon the roll 43.

The. hammer eis formedwitha rearwardlyextending arm ef, .which is fixedto. the rock shaft 10. Projecting forwardlyfrom the shaft 10 .is an yarm|9'providedw'ith'apin 8 adapted to-be .engaged bythe upper endy of anvelevating arm gh Extending forwardly from-theshaft 10 is a curved arm 11to which is pivotally connected, as at 1 1,a ,1 a forwardlyproj eetinglever 12 and a rearwardly-proj ecti i ing lever 13, the forward or freeend of the lever 12 engaging the ratchet teeth 12, fixed to the upper ofthe rolls 41, and Ythe rear' or free end ofthe lever l'engaging theratchet teeth 13,a connected to the roll 43. The lever, 13 has its rearor free Aend held in normal engagement with the ratchet teeth 13athrough the medium of the pulling spring 13b, which is connected at oneend to the lever 13 and at its other end to one of the supports 13c forthe roller 43 and 14. To the arm 9 is fixed a rearward extension 18, andto the upper end of Said extension 18 is attached thel rear end of adistensible and contractible spring .17, whilethe' other end of saidspring 17 is fixed to the lug 17 a, carried by the top 3f) of themachine casing.

A Fromthe foregoing 'construction it is evidenti that when the arm q iselevated, the arm 9 will also be elevated, owing to the engaging ofI thearm g with the pin 8. During such movement, the spring 17 will beextended and when the arm g is moved from engagement with the pin 8 in amanner as hereinafter set forth, the spring 17 will be released, therebycausin the moving of the arm 49 to normal position and theliammer tostrike a blow, so as tomake an impression,v or, 'in

the type or typesd, and thus print the amount.

' When the arm 9 is elevated, rocking the shaft '10, the arm 1 1 Vwill.also be elevated, conse-- quently rocking the.Y levers 12 and 13 andcausing the feed of the paper and the ink ribbon.

ing lug g3 carried on the lower end of an extension g4 forming a part ofa handle g which is mounted upon one end of the shaft 35, and, betweenthe lower end of the arm g and the end of .the extension g4 and upon thelug g3 Vis mounted a. roller 20, which travel'sin4 the path ofan arm rprojecting upwardly from one of the arms 1.

u kFrom the foregoing `construction it is evident that when the handle gis lowered, the arm q will be elevated and the roller 20 will enga e thearm 1' and shift the arms 1 rearward y,'whi'ch will carry' the barftherewith,

so that the saidl bar f will be moved out of v.engagement between theteeth of the wheels c. Whenv the arm q is elevated throughthe medium ofya handle g in the manner as stated, the 'lug 7 will engage the pin` 8and rock the shaft '10 owing tothe fact that 4the lug 7 will 'elevatethe arm 9'.` rDuring the forward movement ofthearm q' the cam portion 15will en- .'gage the lug 16, and the said arm q will be shiftedforwardly, vso that the lug 7 on said y other words, the hammer e willstrike the paper 14 on to the ink ribbon 19 resting above IOO p Thelower end of the 4arm g is connected to a horizontally-extend- IIO arm(j will' be moved out of engagement with the pin 8, thereby releasingthe hammer, so a record can be made4 upon the paper strip. ,i

The' handle g is furthermore provided WithA` i an extension g' carryinga stud 37 which has the upper end of a depen ing arm h.v The vsaidhandle g to their normal position.

lower end of said'arm h has pivotally connected thereto, as at h',alever i, which has its forward end rovided with 'a rod 4. The rear endofthe lleverl has a vertical lever j connected thereto, as at j', andthe lower end of said lever j is substantially hooked shaped, as a't i2.Said end j2 is ada ted'to engage a rod or bar 5 carried on the ibrwardend of a lever c which is pivoted upon the su port 7c carried bythemachine frame.v Wien the handle g is lowered, the extensiong will becarried forwardly, which in turn, will carry the bar g2 forwardly, andallow the upper end of the arm h to also move forwardly, which in turnwill permit the lever i and the rod 4 connected thereto to fall. Thelowering of the forward end of the lever i will elevate the lever j, sothat the hooked end :i2 of said lever j will engage the-bar or rod 5 andlift the forward end of the lever c. The latter carries a spindle le?,which extends at right angles and said lever 7c also carries avertically extending arm c having an angularly-extending spindle c*Ladapted to engage the rear end of a trip lever 25, to be hereinafterreferred to.

A spring connection kf is arranged between the arm k3 and the sup ort cA spring connection k is provide( between the leverlc and the bottom ofthe machine. The spiging connections 7c5 and c are adapted to return`theelements c and 1c to normal position. A

spring connection m is provided between thev bar g2 and the protuberancem2 on the lug g. 'lhis s ring connection insures the rear end of the' arg2 resting upon the support g". A spring connection 30 `is providedbetween the protuberance m2 and a support Sfor moving the handle g toits normal position, which also l insures the moving of the partsconnected to A spring connection m3 is provided between the pivot lt andthe arm Q for retaining the arin g in contact with the pin 8 and lug 16when occasion requires.1 A spring connection m* `is provided forretaining the levery incontact with the bar or rod'5 .when 'occasion sorequires, and a spring connectionl mi is pro-` vided between a dependingarin 40 carried by the lever l and a shaft ml to insure the lowering ofthe lever fi.

Connected to the lug 37 is a rearwardlyextending rod 6, which isarticulated, as at 6, to ailever l, the latter being pivoted at l', andwhich has a cam end 38 to engage a stud 1-2 carried by a lever m. Oneend of the lever mis pivoted, as at 413, andthe other end is bifurcated,as at l, andthe said bifurcated end/l4 straddles a lug l carriedby oneinembei' of an Ll-shaped arm n. The arm n slides along the notchesd 'inthe arms di for the purpose. oi pushing thefarins d3 with the arms duntil it comes to a connecting bar which has been actuated. Suchactuated connectiig bar will then stop or arrest the travel of the arnin. A sliding bearing Z adapted to travel upon the bar Z7 is provided forthe arni n.

Pivotally connected to each of the portions a* of the connecting bar isan L-shaped lever 31 having a stud 31a, and theI said lever 3l ispivotally connected, as at 31". The lower end of each of the levers 31is connected to a rearwardly-extendiiig bar 31C, the latter hav ing itsrear end attached to a distensible and contractible spring 21, saidspring being connected by a hook 21a to a rod 21b carried by a lever rv.The function of the springs 21 is to 3 return the key quadrants and typesectors to normal position. The return movement of the quadrants, (suchmovement being had owing to the action of the springs 21) is limitedthrough the medium of a stop arm s having a protuberance s', which isadapted to be positioned in thepath of a lu'g 22 carried by each of theconnecting bars.

The rear end of each of the arms s has a spring connection between thesame and the shaft m, said spring connection being indicated by thereference character 29.

The action of the wheels c and the quadrants will go on with each itemthat is print- -ed until the number of teeth on any'of the 'the form ofbell cranks with the exception of the lever u in the extreme leftcolumn, such lever u being a one-arm lever. n Each of the levers u ispivoted upon a supporting bar u. The other arm ofeach ofv thelevers u,which is not engaged by one of the protuberances 23, is connected asat'uz, to a triplever iool IIO

25, which is .adapted to engage and shift a lever arm 27 vfrom vunder astop rod 28. A

spring connection uf* is arranged between the trip lever 25 and itsrespective lever u. There is a lever 25 anda lever varm 27 foreach ofthe wheels c with' the exception of the righthand wheel. The uadrantworking with thiswheel is stoppe by la contact plate as this quadrantdoes not require to move an extra tooth for the purpose ofcarrying,there being no quadrant to the right of it, it being noted thatthe'levers 25 and 27 in any par.- ticular column are actuated by theWheelin the column immediately to the right of'it, The lever isprovidedwith a shoulder 24 and the lever arm 27 with a pin 26.

.The shoulder 24 is adapted to be shifted'to one side of and engage thepin 26 so that when the bell crank lever u returns to normal of theprotuberances 23 on the cam t is justy in front of the upper arm of abell crank lever u and as the wheels c move round the cams t move withthem, one'of the protuberances in due course then pressing down thelever u..

The lug 24 on the trip lever 25 then passes to the other side-of the pin26 Von 'the lever 27 belonging to the next quadrant to the. left.

Directly the wheel has passed beyond nine teeth from zero the lever urises up be hind the protuberances 23 of the cam t and the trip lever.25 pulls the arm 27 from undery the rod 28.' The right-hand ends of thelevers s rise under the action of the springs 29. The next quadrant 0 tothe left rises up by the action of the spring 21 a distance of onetooth, taking its corresponding wheel with it.

When the operator releases the lever g the spring 30, in a state oftension, brings this lever and other parts 1n connection therew1th backto their normal position. and any quad-r rants o that may have beenadvanced an ex-'y tra tooth by reason of having carried over, arereturned to normal by the rod 4. The

levers s are pressed down by the rod 5 and the passes toits normalposition' lever 27 then. under 28. y

To prevent the pawls t from being jerked from their position in theteeth of the wheelsl f c when the quadrantsv 0 suddenly come to a .istop, a bar or. rod is provided fitted on its .50

Lipper part with another bar or. rod fc', and connected by vconnections39, 40`to the shaft on 'which is fitted the lever h; When the lhandle orleverfg is actuated the rod i moves and the other rod vassumes ahoripawls 4b from zontal' position preventing the" moving from normal.position.

A quadrant y is fixed to the lever g and-is provided with notches y intowhich a spring' actuated pawl z engages, preventing the le?" ver g fromyreturning toits normal position until the fullf'stroke has beenperformed.4 ,i

Springsy are fitted to the various levers' to keep them in' .theirnormal position.v

Although for the sake of illustration I have only shown four quadrantsand four sets of 'lever g. `pressed the rod 6 is pulled actuating thecam cipher levers d toward front of the pulle into the notch directlyunder it, thus locking the wheels c to their quadrants o and. pulls onthepitman 32, thusdisengaging the rod f from the -wheels c, `thequadrants o then drop down, taking the wheels c with them;` one point 23on each cam t comes into-contact with the lever u. The rod f thenreturns, reloclring the wheels c and quadrants 0 in position to whichthey have dropped thc figures falling in line under the hammer econstituting the total. By this means the total is practically convertedinto a first item placed in the machineafter it has been cleared andbefore the handle g has been pulledand it may be either printed andcarried forward, printed and cleared from machine or cleared frommachine without printing. l

To print total and carry it forward itis necessary to pull the handle gas usual for an item. vT he -total will then be printed and still leftin the machine to be added to anyl subsequent items. f

To clear machine the total lever lw is then pressed down as far as itwill go. The arms 33 and rod 34 with the lever w are fixed to the shaft35 and all move together. When the lever wis depressed the rod 34 ispressed ontothe inclined ridge at the top of the pawls b disengagingthem from the wheels c and when the lever w is allowed to return thequadrants o return vwith it to normal. A spring 36 acting through thearms 33 and. shaft 35 keeps the 'clearingleverinits normal position. l

Errors in'depressingl keys can be corrected ybefore the handle' gisypulledby 'de-pressing the clearing lever w 'as described above. lThisIreturns keys without'l disturbing amount al-v ready in machine. v

vThe rod 6'is connected to a stud 37 on the Wheny the handle or lever g4is de- 38 on the lever Z. This allows the slotted arm m andiwith it theL+shaped arm .n to

'shift toward'the rightfhand yside of the top late. lvThe arm rf [slidesbetween the cipher evers d and the quadrants vo pushingl the 4 plate andyfrom underneath the hammer e. 1 V

As shown thedrawings the quadrants 0 pulled all the ciphers d would Ibeshifted and v.nothing whatever printed.

v If' any vquadrant o. when pulled forward' as in` Setting up an item`when the handle is lpulled the lever a would travel, shifting all thectiiphers d to the left of that quadrant o forward, and being preventedby iml are vncrmal and therefore,"ifffhandlej were ,bined With pingingon the side of said quadrant from traveling any further, leaves theciphers to to be printed.
